// Select the main list and add the class "hasSubmenu" in each LI that contains an UL 
$('ul').each(function(){ 
    $this = $(this); 
    $this.find("li").has("ul").addClass("hasSubmenu"); 
    $this.find("li").has("ul").css('collapsed', 'true'); 
}); 
// Find the last li in each level 
$('li:last-child').each(function(){ 
    $this = $(this); 
    // Check if LI has children 
    if ($this.children('ul').length === 0){ 
    // Add border-left in every UL where the last LI has not children 
    $this.closest('ul').css("border-left", "1px solid gray"); 
    } else { 
    // Add border in child LI, except in the last one 
    $this.closest('ul').children("li").not(":last").css("border-left","1px solid gray"); 
    // Add the class "addBorderBefore" to create the pseudo-element :defore in the last li 
    $this.closest('ul').children("li").last().children("a").addClass("addBorderBefore"); 
    // Add margin in the first level of the list 
    $this.closest('ul').css("margin-top","20px"); 
    // Add margin in other levels of the list 
    $this.closest('ul').find("li").children("ul").css("margin-top","20px"); 
    }; 
}); 
// Add bold in li and levels above 
$('ul li').each(function(){ 
    $this = $(this); 
    $this.mouseenter(function(){ 
    $(this).children("a").css({"font-weight":"bold","color":"#336b9b"});
